(Data may be adjusted from the default setting at the factory. Refer to the factory setting sheets
enclosed. You can find it under the jammed paper removal decal.)
DFU: Design/Factory Use only
Do not touch these SP modes in the field.
A sharp (#) to the right hand side of the mode number column means that the main switch must be
turned off and on to effect the setting change.
An asterisk (*) to the right hand side of the mode number column means that this mode is stored
in the NVRAM. If you do a RAM clear, this SP mode will be reset to the default value. "ENG" and
"CTL" show which NVRAM contains the data.
§
ENG: NVRAM on the BCU board
§
CTL: NVRAM on the controller board
The settings of each SP mode are explained in the right-hand column of the SP table in the
following way.
[Adjustable range / Default setting / Step] Alphanumeric
§
If "Alphanumeric" is written to the right of the bracket as shown above, the setting of the
SP mode shows on the screen using alphanumeric characters instead of only numbers.
However, the settings in the bracket in the SP mode table are explained by using only the
numbers.
SSP: This denotes a "Special Service Program" mode setting.
